Description
Technical field
The present invention relates to the technical fields of construction material, more particularly to a kind of crack resistence porous brick and preparation method thereof.
Background technique
It is well known that porous brick refers to using clay, shale, flyash as primary raw material, it is porous made of being formed, being roasted
Brick, hole ratio are equal to or more than 15%, and pass is circular hole or non-circular hole, the size in hole is small and quantity more than be known as porous brick, it is main
To be suitable for bearing wall.
Porous brick, hollow brick are compared with traditional solid brick, but building weight reduction 1/3 or so, save fuel 10-
20%, firing rate is high, save the cost, improves service efficiency, can improve the heat-insulated and sound insulation turned it is new more can, there is good warp
Ji meaning, but it is primary raw material that existing porous brick, which mostly uses clay, shale etc., greatly destroys ecological environment, therefore,
How using waste resource production porous brick, achieving the purpose that economize on resources to be to continue with is solved the problems, such as, and existing porous
Brick is easy cracking when in use, and service life is lower.
Gangue is the solid waste discharged during coal mining process and coal washing, be one kind in coalification course with coal seam companion
A kind of lower, harder than the coal black and gray rock of raw phosphorus content；After gas generator gasified raw material coal, solid residue is obtained,
We are known as clinker or ashes, and clinker itself is slightly with or without hydraulic gelling property, but it is existing for the levigate later moisture
In the case of, especially under the conditions of steam curing, participates in calcium hydroxide or other hydroxide chemically react.And generate tool
There is the compound of hydraulic gelling property.So it can be used to be usually used in producing cinder or cinder concrete is big as construction material
Clinker can also be used to repair the roads or make the heat preservation in house, acoustic material by pattern plate etc.；Red mud is that aluminium industry extracts aluminium oxide
When the pollution waste residue that is discharged, also known as red soil, from refining the industrial solid wastes being discharged after aluminium oxide in bauxite.It is a large amount of red
Mud sufficiently effective cannot utilize, and can only stack by the stockyard of large area, occupy a large amount of soils, also cause sternly to environment
The pollution of weight.About 70,000,000 tons of the red mud that the whole world generates every year, the red mud that China generates every year is 30,000,000 tons or more, largely
The generation of red mud causes various influences directly or indirectly to the production of the mankind, life, so subtracting to greatest extent
The yield and harm of few red mud, realize by all kinds of means, the recycling of quantity greatly it is extremely urgent.
